Gday again I am back. For awhile there I was preverted into nitro bikes and fast 1/8 scale onroads. Well boats and shiny propellers have seen me return.
The tunnel has had a face lift. Now features RC-Hydros Victory esc, Lightning 700 neo X can, REK drive and TP 2100 4s lipo, water cooled motor/esc & O.S. prop 42mm.
Goes really well now. Does a mono off the start and scoots along very quickly and sits still on the plane no worries. First turns just spun completely around. We set the throw on the steering down to 30% which was plenty. Back out and turning with authority at speed. Really happy.
A few things: We ran 4s lipo when we should have been running a 4s2p. The battery got pretty warm. PLUS, we were running a 42mm prop when we should have started with a 38 or 40. We set the Hydro to stop @ approx 12.8v as well, thanks Andy. The boat is not fitted with recovery pads and the angle of the outdrive is a tiny bit lowered. While it looks absolutley realistic doing its mono starts we ended up hurling the boat into the water like the pros to lower massive amp draw/battery abuse. The lipo pack is right up the front of the boat as it is very light. Boat has 21g of lead in the nose too.
This has been a fun project and I now find myself mimicking the layout of the TS2 into the Dumas. I applied a thin layer off glass to the bottom back third of the tunnel and got it really smooth and square, massivly reinforced transom with ply and thin ali sheet. Some props arrived yesterday from Andy and we are going to try this weekend, x1440. They look Awesome. Funny thing: Tried sharpening a x440, spent 1 hour with fine sandpaper, autosol, dremel etc. Boat run: Rolled it first corner lol. So much for my prop sharpening skills!!!
Sorry to be so long and I hope you like the end result. Next is brushless TS2... Hmmm
Edit: I used black contact for the window. Made a paper template then traced onto the adhesive contact. Also, if you choose to mount the motor raised like this, you can get 2.5 cm spacers from Jaycar(electronics shop in Australia) for $3. Aluminum for face plate can also be purchased there cheap. FYI.
Bye
Peter
PS - So as not to ruin the EP-1 thread, I put the Titan 14v into that for something, someday????
